]]>Reveal for Multi-Treenut detects 5 to 10 ppm of almond, hazelnut, pecan, walnut, cashew, and pistachio residues on environmental surfaces, as well as in rinses. The test can aid food manufacturers in cleaning validations or verification of existing procedures to prevent cross-contamination of tree nuts within their manufacturing facilities. Users simply dip the test’s device in an extracted sample and wait 10 minutes. If two lines develop, the test is positive for one or more of the six tree nuts. If only one line develops, the test is negative. Neogen Corp., 800-234-5333,www.neogen.com.

]]>MaxSignal Histamine ELISA Test Kit, for the screening of histamine in fish and fishmeal, uses a 15-minute aqueous extraction method that doesn’t require heating or organic extraction steps, and an assay protocol that only requires 25 minutes to simplify histamine detection. The kit can specifically detect as little as 3 ppm of histamine in fresh or frozen fish samples and 30 ppm in fishmeal. It can provide detection over a range of histamine concentrations, 3 to 270 ppm for fish samples. Bioo Scientific, 888-208-2246,www.biooscientific.com.

]]>Macrowave Pasteurization Systems are ideal for batch or conveyorized applications for bagged or bulk product. In a Macrowave heating system, an RF generator creates an alternating electric field between two electrodes. The material to be treated is conveyed through an electrode array where this alternating energy causes polar molecules in material to continuously reorient them to face opposite poles. The resulting friction causes the material to heat both rapidly and uniformly throughout its entire mass. Radio Frequency Co., 508-376-9555,www.radiofrequency.com.

]]>The Eagle Bulk 415 PRO system features a cupped conveyor, the raised edges of which can promote a more uniform product depth across the belt as well as reduce waste by preventing product spilling onto the floor. This, combined with Eagle’s Material Discrimination X-ray technology, which discriminates materials by their chemical composition rather than relying on busy grey scale images, can optimize the detection of contaminants, from glass, metal, and some plastics, to mineral stones and rocks. The system is ideal for production lines processing nuts, grains, granola, sugar, cereals, coffee, and other high-volume bulk products. Eagle Product Inspection, 877-379-1670,www.eaglepi.com.

]]>The HI2002 pH/ORP, HI2003 EC/TDS/Salinity, and HI2004 DO edge meters are thin and lightweight, measuring half an inch thick and weighing 9 oz. This design allows them to be used like benchtop or portable meters, which can attach to walls to free up bench space in laboratories. The meters feature a 5.5-in. LCD with a wide viewing angle, capacitive touch keypad, dual USB ports, cradle with swivel arm electrode holder, and wall mount. All edge meters use digital smart electrodes that store sensor type, ID, and calibration information. These digital electrodes also have a 3.5 mm connector.Hanna Instruments, Inc., 800-426-6287, www.hannainst.com.

]]>The AquaLab TDL uses tunable diode laser technology to measure water activity in samples. Water activity of food products is frequently measured to determine susceptibility to mold and microbial spoilage, to predict reactions that end shelf life, and to set and monitor quality in products affected by moisture. The tunable diode laser locks onto a single absorption wavelength of water and reads only that band. Because it is specific to water and negligibly absorbed by molecules of other gases, the sensor is not affected by volatiles. Decagon Devices, Inc., 509-332-2756, www.decagon.com.

]]>Adulterant Screen software can help food industry professionals evaluate the integrity of food ingredients to guard against existing and potential food adulteration threats. The software performs rapid, targeted, and non-targeted screening for several types of adulterants. Its green light/red light “pass/fail” results system can allow for easy implementation, regardless of the knowledge level of its users. Adulterant Screen software, when paired with PerkinElmer’s Fourier Transform Infrared and Near Infrared spectroscopy instruments, creates a combined hardware and software system that can confirm authenticity and perform nutritional analysis in a single step.

The SaniTimer attaches to any standard handwashing sink faucet to ensure staff rinse, lather, and wash their hands for the full 20 seconds recommended by the CDC to avoid the spread of bacteria. It automatically begins a 30-second countdown—the extra 10 seconds account for an individual’s preferred handwash prep—shown on an LED display as soon as the water is turned on. At the end of the cycle, the SaniTimer beeps to alert the handwashing user and resets itself to 30 seconds for the next user. The device works with pedal sinks as well as hands-free sinks.

]]>The hygienically designed Immersion Spiral Freezer is a two-stage cryogenic freezer with a space-saving design that can process more than 20,000 lbs. per hour. The first stage applies an instant crust freeze with liquid nitrogen to maximize yield and protect surface integrity. The cold gases from the first stage travel into the second stage to maximize the use of BTUs. Key uses include meat and poultry, glazed and marinated products, and seafood. The liquid immersion and spiral freezer stages can be custom configured to meet specific requirements.Linde LLC, 800-755-9277, www.lindefood.com.
